Keyuan Packaging 4.1oz/120ml 24-400 Methylstyrene Cylinder Airless Bottle with PP Lotion Pump and ABS Overcap

What this packaging is

A cylinder silhouette and vacuum-driven airless mechanism make this 4.1oz/120ml lotion pump bottle a strong fit for face serums and moisturizers that need real protection from air exposure. Built from methylstyrene (MS) plastic, the bottle delivers a glass-like weight and feel without the fragility. The integrated PP lotion pump and ABS overcap ship as a complete set, reducing vendor coordination. Every dose is pushed upward by the airless system, cutting product waste and keeping formulas stable from first pump to last. Surface decoration options include hot stamping, screen printing, and rubber painting, giving brand teams meaningful shelf differentiation.

Why brands choose this

• Airless mechanism protects formula integrity shelf to last drop: The vacuum-driven pump isolates contents from air contact throughout the product's life, not just at the start. For oxidation-sensitive serums and moisturizers, that stability story is a genuine consumer confidence signal and a formulation win.
• MS material brings premium, glass-like weight to a plastic format: Methylstyrene reads heavier and more substantial in the hand than standard PET or PP, giving this bottle an elevated sensory cue that aligns with the positioning of prestige skincare without the cost and fragility of glass.
• Complete pump-and-cap set simplifies the development timeline: The PP lotion pump and ABS overcap are included as a matched system, which means fewer vendors to coordinate, faster compatibility testing, and a cleaner path from sampling to production for brand teams running tight launch schedules.
